Product Details

TotalBoat Penetrating Epoxy is a low-viscosity wood rot restoration and repair solution that seals deeper & cures stronger than industry-leading penetrating epoxies. It has no VOCs, no odor & is 100% waterproof once cured.

This 2:1 system is ideal for restoring rotten or damaged wood, or sealing new wood for lasting protection against humidity, salt, mold & mildew. It works by gluing cellulose (wood) fibers back together, sealing a bare, porous wood surface from the inside out. Double the penetrating power by mixing acetone with the epoxy resin solution in equal volume. Easy to apply by brush, roller, or inject via syringe. Surfaces may be painted or varnished after light sanding.

Choose from Traditional (65-90 F) or Cold Weather (40-65 F) formulas in Pint, Quart, 1/2 Gallon & Gallon kits.

Info & Guides

NO VOCS, NO SMELL.

Cleanup is easy. Wear latex gloves, wash off with soap and water. No solvents required.


APPLICATION NOTE: The wood must be bare and unfinished. Also, TotalBoat Penetrating Epoxy will not penetrate and level well when applied over some stains. Always test an area first. DO NOT USE on top of Minwax oil-based stains.


TotalBoat Cold Weather Penetrating Epoxy is perfect for use during the colder seasons. Compared to our traditional TotalBoat Penetrating Epoxy, our Cold Weather formula offers similar performance characteristics, but cures completely and reliably in cooler temperatures. Its tack-free properties also allow you to sand sooner.

WARNING: TotalBoat Cold Weather Penetrating Epoxy should not be used as a fast-cure epoxy in warmer temperature conditions because doing so can be unsafe and result in premature exotherm, brittleness, and improper curing.

Application Temperature Ranges:

  • Traditional formula - 65-90°F
  • Cold Weather formula - 40-65°F

I will buy this product often.
By jayhawk714 from Featherville, Idaho

Verified Purchase

I use this on all of my epoxy projects. It is a very easy to mix and apply. It is a lot thinner that the resin and hardener so it brushes on very easy. It will soak in deep to the wood fibers and seals against air bubbles in your pour.

Bottom Line Yes, I would recommend to a friend

I would not buy again
By Scott from Ellsworth, ME

Verified Purchase

I read the directions carefully. I watched a video. Nonetheless, it didn't work as I had hoped. First, after about 15 minutes the mixed product (Part A and B) started to heat up. It even smoked and the cup became too hot to hold. Second, shortly after application the product started to bubble on the wood finish.

Bottom Line No, I would not recommend to a friend

Easy to apply and cures well
By Jim from Heathsville, VA

Verified Purchase

I used this on my sailboat's toe rail and on a plywood seat. In both cases I stripped the wood first. Then varnished the toerail with Halcyon Amber, or painted the plywood with bilge paint. Happy with both scenarios. I got the pumps so I can use them easily as needed.

Bottom Line Yes, I would recommend to a friend

Works well. Hardener leaked a little in transport.
By Lars from Locke, NY

Verified Purchase

Non-marine application, but very effective as a penetrative coating. Label of hardener was illegible upon opening package, due to slightly leaking. Hardener is about as non-viscous as water, or even thinner. But overall I am satisfied.

Bottom Line Yes, I would recommend to a friend

Excellent product, excellent service, happy.
By Linda from Gulfport, Mississippi

Verified Purchase

I needed epoxy for several small jobs, so I ordered a gallon and got free shipping -- can't beat that. It's good to have some on hand, and the two components keep well in storage, so I have some left over for anything else that pops up. Linda

Worked Great!
By Construction Momma from Central Valley - California

Verified Purchase

We installed a 3 inch thick redwood slab for a bar top, put two coats on and it looks fantastic. The product brought out all the wood grains and colors. It has the shiny coat that you can slide a beer across. Thank you and keep up the good work on this product!

This works amazingly well.
By DIY Mike from Hopinton, Rhode Island

Verified Purchase

I used this product to repair water damage to an older travel trailer that had a leaking roof. Some of the wood structure was softened and weak from water damage. I used this product to revive the integrity of the wood, and protect all the new material I replaced. I used a piece of the wood I removed as a test sample and I was impressed how far the epoxy penetrated, and how much stronger the wood was after treating it with the epoxy.

Bottom Line Yes, I would recommend to a friend
